Because he hits the Omega hard, Warren’s everyday mallet requires an extremely durable 100% nylon yarn, secured with three separate stitching procedures: a proprietary internal stitching procedure that you can’t see, followed by external stitching top and bottom plus reinforcement bands. It’s built on a thermoplastic disk with two layers of rubber under the computer-controlled winding. When you first play with these mallets you might conclude they are too soft for you. Play and play and they will eventually hit a sweet spot and stay that way for a very long time. No worries, they won’t wear out or fray!
